Structure and Function of Alkane Monooxygenase (AlkB). [PDF]
Accounts of Chemical Research, 2023 ConspectusEvery year, perhaps as much as 800 million tons of hydrocarbons enters the environment; alkanes make up a large percentage of it. Most are transformed by organisms that utilize these molecules as sources of energy and carbon.

DNA repair by bacterial AlkB proteins
Research in Microbiology, 2003 The Escherichia coli AlkB protein is an iron- and 2-oxoglutarate-dependent oxygenase, repairing 1-methyladenine and 3-methylcytosine lesions in DNA. AlkB homologues are present in a number of bacterial species, and some bacteria have two different AlkB proteins.

Aberrant activity of the DNA repair enzyme AlkB
Journal of Inorganic Biochemistry, 2004Escherichia coli AlkB is a DNA/RNA repair enzyme containing a mononuclear Fe(II) site that couples the oxidative decomposition of alpha-ketoglutarate (alphaKG) to the hydroxylation of 1-methyladenine or 3-methylcytosine lesions in DNA or RNA, resulting in release of formaldehyde and restoration of the normal bases.

Pseudomonas aeruginosa strains that grow on crude oil as the sole source of carbon and energy were isolated from an environment in Morocco polluted by petroleum refinery effluents. The twenty isolates grew on saturated alkanes from C12 to C22. Three of the isolates were also able to grow on low molecular weight C6 to C10 n-alkanes, but the other 17 ...

AlkB demethylases flip out in different ways
DNA Repair, 2008Aberrant methylations in DNA are repaired by base excision repair (BER) and direct repair by a methyltransferase or by an oxidative demethylase of the AlkB type. Yang et al. [Nature 452 (2008) 961-966] have now solved the crystal structure of AlkB and human AlkB homolog 2 (hABH2) in complex with DNA using an ingenious crosslinking strategy to stabilize
